By chewing till the flavor changes you know that you have converted the complex carbohydrates into simple sugars... why is this good?
I don't know! I'm a college drop out!
I will say this about flavor changes though, I have been working on this coconut for 3 days now almost finished it. Before eating it, I had a thought "don't eat it now" but disregarded it thinking I'll have melon for dinner and don't need the tasty satisfaction of coconut tonight. So I began to chew the coconut and apple and the coconut which had been tasting great even this morning, now began to taste a little like soap! Yuck. So I stopped eating it and will follow my intuition more closely next time. Apples still taste delicious!
